This paper intends to clarify the process of the Perceptual Assimilation Model (PAM) predicting the patterns of human categorical speech perception in audio perception of second language (L2) speech signals. The original stage of categorizing acoustic stimuli in the L2 signal often involves assimilation from L1 categories. Whether L1 sounds will assimilate(More)
Category formation of human perception is a vital part of cognitive ability. The disciplines of neuroscience and linguistics, however, seldom mention it in the marrying of the two. The present study reviews the neurological view of language acquisition as normalization of incoming speech signal, and attempts to suggest how speech sound category formation(More)
This study aims to review, through experiment proof of a salient effect of articulatory gestures on L2 perception, the time-honored but still put-to-sideways motor theory of speech perception. On one hand, previous studies in support to motor theory were largely done by tests of mismatch in duplex perception of acoustic/speech data; or by L1 development(More)
The study of second language speech perception usually put L1-L2 phonological mapping as the rule of thumb in predicting learning outcome, and seldom included more fine-grained aspects such as frequency. This study examines how frequency of sounds in L1 may influence L2 segmental production and perception, with examples from English learners native to two(More)
